A water quality monitoring survey during the wet-weather seasonal period (January to June 1976) was conducted in the Kaneohe Bay area as part of the U.S. Army, Corps of Engineers Kaneohe Bay Urban Water Resources Study. ...

An inventory of benthic and planktonic marine communities at Mōkapu Point, Oahu, compiled in July to August 1975, prior to the completion of an outfall and discharge of secondary sewage effluent, has been prepared for the ...

The objective of the project was the investigation of the percolate rate and the disposition of nitrogen from a laboratory soil column when chlorinated secondary sewage effluent was applied under both continuous and ...

In recent times the increased influx of nutrients and organic matter as a result of man's activities into some waterways has resulted in the accelerated eutrophication of these waters. This has been found to be the case ...

A marine survey was conducted in the vicinity of the present and proposed
Wai'anae sewage ocean outfall site on the southwest coast of 0'ahu, Hawai'i. The survey at depths of 6 to 30 m (20-100 ft) characterized quantitatively ...

The goal of this project was to provide information to the County of Hawaii and to the state for the intelligent management of the marine and coastal resources of West Hawaii, particularly the South Kohala and North Kona ...

Dugan, Gordon L.(Water Resources Research Center, University of Hawaii at Manoa, 1977-02)

The Hawaii Environmental Simulation Laboratory (HESL), since its establishment in the spring of 1971, has attempted to simulate some of the consequences of alternative land-use economic decisions which include, as one of ...

Injection of wastes into a Ghyben-Herzberg groundwater system presents unique problems because the waste effluents are normally injected into the salt or brackish water underlying the fresh Ghyben-Herzberg lens. Because ...

Williams, John A.(Water Resources Research Center, University of Hawaii at Manoa, 1977-05)

A Hele-Shaw model was employed in conducting preliminary studies of waste water injection into a fresh-saline water system. Three different field conditions were simulated: injection under static conditions, injection into ...

Ekern, Paul C.(Water Resources Research Center, University of Hawaii at Manoa, 1977-06)

The daily water budget of drip-irrigated sugarcane at Kunia, Oahu, was measured in large hydraulic load cell lysimeters. The 10-mo plant crop period was extrapolated to 109 am (43 in.}/12-mo water use. Extrapolation from ...

Jiracek, George R.(Water Resources Research Center, University of Hawaii at Manoa, 1967-08)

The reported high values of resistivity in the near surface zones in semi-arid regions on the island of Hawaii motivated research into the feasibility of using radio waves to sound the depth to the ground water table. Field ...

The basic objectives of this study were to determine the average annual recharge to the groundwater body and the fresh groundwater discharge at the coastline, as well as the aquifer characteristics for an arid area
located ...

Phase II-A is a project that is an extension of a recently completed 4-yr project (July 1975) entitled "Recycling of Sewage Effluent by Irrigation: A Field Study on Oahu," hereinafter referred to as Phase I. The main purpose ...

Maps of diurnal rainfall patterns based on hourly rainfall records are presented for the six major Hawaiian islands. The resulting rainfall distributions demonstrate the complexity of the interaction between trade winds ...

Mink, John F.(Water Resources Research Center, University of Hawaii at Manoa, 1977-09)

The research of the Water Resources Research Center covers all aspects of water resources investigations, in the course of which considerable new significant data are generated and older data reevaluated. These data are ...

The adequate design of a storm drainage system depends upon the proper estimation of various peak discharges (produced from a given storm) along the drainage network. The objective of this study is the development of a ...

Increased water consumption on O'ahu has encouraged the use of treated sewage effluent for irrigation. This study seeks to identify organic compounds in treated effluent and to determine if such compounds are adosrbed by ...

A large-scale pilot rotating disc treatment system was tested at the City and County of Honolulu Pacific Palisades Municipal Wastewater Treatment Facility, to evaluate its treatment effectiveness and capabilities, and to ...

Numerous stream mouths on O'ahu are affected by sand berm blockages which prevent free flow of storm waters to the ocean and cause the stream water level to rise rapidly; often overflowing of the stream banks and flooding ...
